Exact Sciences Investigates Alleged Data Breach Following ShinyHunters Ransomware Claim On July 15, 2026, the ransomware group ShinyHunters claimed responsibility for an alleged cyberattack targeting Exact Sciences, a leading provider of diagnostic screening tests, including Cologuard and Cancerguard. The breach was announced via a dark web post the same day, though details about the scope, compromised data, or attack methodology remain unconfirmed. Attorneys affiliated with ClassAction.org have launched an investigation into the incident, seeking potential plaintiffs including current and former employees and customers who suspect their personal or sensitive information may have been exposed. A class action lawsuit, if filed and successful, could seek compensation for privacy violations, financial losses, and other damages. Exact Sciences, which was acquired by Remember (the acquiring entity’s name is unclear in the report), has not publicly disclosed further details about the breach. The investigation is ongoing, with legal representatives gathering testimonies to assess the viability of a lawsuit. No additional information about the nature of the exposed data or the number of affected individuals has been released. The incident follows a pattern of ransomware attacks targeting healthcare and diagnostic service providers, underscoring persistent vulnerabilities in the sector. Previous breaches in 2026, including those at Firstsource Healthplans, The Estée Lauder Companies, and The Washington Post, highlight the growing threat landscape for organizations handling sensitive data.

Abbott Discloses Cyberattack on Cancer Diagnostics Business Abbott Laboratories confirmed a cyberattack targeting its cancer diagnostics business, which includes systems from Exact Sciences a company it acquired in a $21 billion deal earlier this year. The incident involved unauthorized access to a limited number of internal systems, though Abbott stated that the attack did not disrupt business operations, product availability, manufacturing, or patient services. The company also noted that no other Abbott businesses, sites, or systems were affected and that it does not expect a material financial impact. Details on the type of information accessed or the timeline of the attack remain undisclosed. Upon discovery, Abbott engaged third-party cybersecurity experts and notified law enforcement, with an ongoing investigation into the breach. The legacy systems of Exact Sciences were reported to be separate from Abbott’s infrastructure. This incident follows a recent surge in cyberattacks targeting medtech companies, including a March breach at Stryker and a separate attack on Medtronic. The manufacturing sector, particularly healthcare-related industries, has seen increased targeting due to vulnerabilities in IT/OT convergence, prompting leaders to bolster cybersecurity defenses. Abbott’s disclosure underscores the growing cyber risks facing critical industries amid evolving threat landscapes.
